US President Joe Biden received an emotional welcome on the first night of the Democratic National Convention in Chicago. Biden said selecting Kamala Harris to be his vice president was the “best decision” ever.

Making a brief, unannounced onstage appearance, US Vice President Kamala Harris said she was “forever grateful” to President Joe Biden. 

“I want to kick us off by celebrating our incredible president, Joe Biden,” she said to cheers.

“Joe, thank you for your historic leadership, for your lifetime of service to our nation.”

Harris’ remarks came shortly before Biden was scheduled to address the event.
